3MM CS X 159.5MM ID BLACK FKM 75D

The V3X159.5 is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 159.5 mm (6.28 in), a cross section of 3 mm (0.118 in), and an outside diameter of 165.5 mm (6.52 in). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Viton® (FKM) is specified here for very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. The compound resists many acids, chlorinated solvents, and petroleum oils and fuels. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with ketones and esters or low-molecular-weight organic acids.

Maintenance and OEM teams specify it across high-temperature process equipment, chemical processing, and semiconductor equipment.

V3X159.5 ships individually. Unit weight is approximately 6.5438 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
